Hypercore

Features

Verifiable Storage - Maintains data in a Merkle tree structure to provide cryptographic proofs of integrity and authenticity.
Append-Only Log Storage - Implements a distributed append-only log structure for synchronization across peer-to-peer networks.
Sparse Replication - Supports bandwidth-efficient replication by allowing peers to download only the specific log ranges they need.
Sparse Replication - Reduces bandwidth usage by downloading only specific ranges or individual blocks of data instead of the entire log.
State Synchronization - Creates network streams to synchronize log state and blocks between local and remote peers.
Peer-to-Peer Database Replication - Synchronizes log state between instances by establishing replication streams to exchange missing data blocks.
Sparse Replication - Allows peers to fetch only required ranges of data instead of the full log to reduce bandwidth.
Cryptographic Log Signing - Secures the log by requiring every append or truncate operation to be signed by a private key.
Log Integrity Validation - Generates Merkle Tree hashes of the log to validate the overall authenticity and integrity of the data stream.
Merkle Tree Utilities - Generates Merkle tree hashes and proofs to verify that specific blocks or ranges have not been tampered with.
Merkle-Tree Data Integrity - Uses Merkle trees to provide cryptographic proofs that specific data blocks remain authentic and untampered.
Remote Block Fetching - Enables fetching of individual data blocks by index from remote peers.
Log Snapshots - Enables opening read-only sessions of a log at a specific length that remains frozen as data grows.
Log Truncation - Supports shortening logs to a specific length and signing the truncation to create data forks.
Log Content Streaming - Reads ranges of data or bytes as continuous streams supporting discrete ranges and live updates.
Remote Data Retrieval - Provides utilities for retrieving specific blocks or ranges of bytes from remote peers.
Range-Based Stream Queries - Supports retrieving specific segments of the log as continuous streams based on defined ranges.
Peer-to-Peer Networking Extensions - Allows the creation of encrypted protocol streams and registration of custom extensions for peer-to-peer communication.
Block Encryption - Applies encryption to individual blocks using specific keys to ensure the privacy of stored data.
Message Encryption - Implements encrypted protocol streams for secure message exchange between network participants.

Dat is a peer-to-peer file synchronization tool that combines an append-only, hash-addressed log with Merkle tree verification, cryptographic access keys, live streaming replication, and swarm networking for sparse, versioned file sharing. It stores file data and metadata in a cryptographically signed, versioned append-only log where each entry is identified by its hash, and uses public-key cryptography to secure archives with separate read and write keys. The tool enables live streaming replication of data between peers as entries are appended, with Merkle tree integrity verification that su
